What is Double-crush syndrome?
There is some experimental and clinical evidence that once a nerve is damaged, it becomes more susceptible to injury elsewhere. This concept remains controversial, however. Examples of this include: A pinched nerve in the neck from a herniated disk increasing the likelihood of carpal tunnel syndrome in the hand, and Patients with diabetic neuropathy having an increased incidence of nerve entrapments in the extremities. If there are two points of nerve compression, then decompression of both regions may be indicated to optimize recovery. Additionally, if an injured nerve is regenerating down a limb, this regeneration may be slowed at natural points of nerve compression (e.g., elbow, wrist).
